車両の大型化を避けることはできない。Conventional towing tractors of this type have a removable towing bar, and when moving an aircraft, the tractor and the towed aircraft are connected by a towing bar, and the tractor is operated to tow the aircraft to the desired location. In order to increase the traction force, it is necessary to increase the motor capacity of the tractor itself as well as its vehicle weight, and therefore, it is impossible to avoid increasing the size of the vehicle.

本発明の実施例は以上で構成され、航空機を移動させる
には先づ車両の運転によってこれを航空機に近接させ昇
降プラット６の先端をその被牽引航空機のノーズタイヤ
の前部に対向させる。The embodiment of the present invention is constructed as described above, and in order to move the aircraft, the vehicle is first brought close to the aircraft and the tip of the lifting platform 6 is opposed to the front part of the nose tire of the towed aircraft.

タイヤの前面下部に対接させる。Next, the piston rods of the lifting cylinders 8, 8' are extended to push the brat 6 down to the ground surface, and then the vehicle is driven again to bring the tip of the lifting gracitro into contact with the front lower part of the nose tire of the aircraft.
この状態で引込用シリンダーを伸長させてそのピストン
ロッドの先端の係合部を航空機のノーズギヤ一部の牽引

そのピストンロッドを引キ込ませる。In this state, extend the retraction cylinder so that the engaging part at the tip of the piston rod engages with the towing part of a part of the nose gear of the aircraft, and then operate the retraction cylinder to retract the piston rod. Let it happen.
これによってその航空機は車両の方向に向って引き込ま
れ、その航空機におけるノーズタイヤが昇降プラット６
上に乗り移ることとなる。This causes the aircraft to be pulled towards the vehicle, causing the aircraft's nose tires to move onto the elevator platform 6.
It will move to the top.

うことができる。Next, by raising the lifting platform by operating the lifting cylinders 8 and 8', the aircraft will be lifted at the nose tire, and by driving the vehicle in this manner, the movement of the aircraft will be controlled by the vehicle. This can be done with some of the aircraft's own weight added to it.
実施例では航空機のノーズタイヤ部分を昇降プラット上

、取外し作業が安易になると同時に被牽引航空機との位
置を合せる為のステヤリング操作が簡単になり作業時間
が短縮されることとなる。The present invention thus provides a vehicle equipped with an elevating platform for lifting the towed aircraft by its nose tire, and a retraction device such as a cylinder for retracting the nose tire onto the elevating platform. The aircraft can be moved with part of the weight of the towed aircraft being transferred to the vehicle, increasing the ground pressure of the vehicle by that amount. Therefore, the weight of the vehicle can be reduced and the vehicle can be made smaller, making it cheaper. In addition, the towing bracket can be replaced with a compact towing bracket, which makes the installation and removal work easier, although the work of installing and removing the towing bar during aircraft movement work is not completely eliminated. At the same time, the steering operation to align with the towed aircraft becomes easier, reducing work time.
更には航空機牽引作業がノーズギヤ一部に車両を近接さ
せた状態で行なえるので安定した牽引が行なえると共に
牽引走行が容易であり、さらにまた航空機に対する牽引

引の場合の引込装置を航空機に繋合させるための牽引金
具は簡単すものを航空機の前部に備えるのみでその目的
を達成することができる。Furthermore, since aircraft towing work can be carried out with the vehicle close to a part of the nose gear, stable towing is possible and towing is easy.Furthermore, the traction force for the aircraft is limited to the aircraft and the elevating platform, which are made up of only aircraft retracting devices. Therefore, when towing a small or medium-sized aircraft, the purpose can be achieved by simply providing a simple tow fitting for connecting the towing device to the aircraft at the front of the aircraft. Can be done.
